AUGUSTUS s. van HOUTEN, or NEWARK, NEW JERSEY,

ARTIFICIAL DENTURE V.application led December To aZ-Z whom t concern:

Be it known that l, AUGUSTUS-3S. VAN Henman; a citizen of the UnitedStates of America, residing at Newark, in `the county of Essex and Stateof New Jersey, have invented certain new and useful improvements inArtilicial Dentures, of which the following is a specification.

My invention relates to the construction of attachments for fasteningremovable den tures to natural teeth.

Some of the objects of my invention are: first; the construction of aneflicient connection between a bridge; plate or similar devicecontaining artificial teeth and a clasp or other removable means ofattachment to a natural tooth; second, to join an artificial denturewith a natural tooth in such manner that the denture may be readily andcompletelyremoved from the mouth; third2 to form a flexible attachmentbetweenv an artificial denture and a natural tooth and fourth,toconstruct the connection between an artificial denture and anaturalxtooth in such manner that the denture may have the necessaryvertical, lateral; rocking7 and angular movement with respect tothenatural tooth that is desired to prevent Stress being placed on thenatural tooth and may have proper contact with the gum. Y

With these and other objects` in view, one embodiment of my invention isshown in the accompanying drawings, in which:

Figure 1 is a perspective of a conventional representation of the gum ofthe lower jaw with an artificial denture on one side connected to thenatural teeth and with the denture on the opposite side omitted;

Figure 2 is a perspective of a fragment of an artificial denture showingthe location ona tooth on said denture of a part of the connectingmeans;

Figure 3 is a perspective of two parts of my connection shown separatelyand independently of a tooth and an articial denture' Figure 4 is avertical Section through my device and a part of the artificial denture;

Figure 5 is a Section on line 5 5 of Figure 4;

Figure 6 is a perspective showing the clasp and a modified form ofconnection and Figure 7 iS a section Similar to Figure 4 showing amodified form of connection and omitting the artificial denture.

In Figure 1 of the drawings there appears i, 1923. serial No. 678,013."Vf

a part of the representation of Va kconyentional lower Jaw and gums ,lsuch as are commonly used in illustrating the construction and use ofartificial dentures. f Thejaw shows natural teeth 2 and anartificialfden- "tureB having teeth l therein. One-half orf-theartificial denture having a` lingual 'bar 5 to be used to connect thetwo parts of the denture together lwhen the denture is :complete isillustrated; one-half `being omitted to show the construction andposition of vthe connection. The part of the denture omitted. fromFigure 1 is indicatedl fragmentary in Figure 2. Attached to a clasp 6comprising the' usual band 7 and a cusp 8,iifwa Vcuspbe desired, is aplate 9. any desired manner as by soldering or casting. This plate is`flat, relatively thin and rectangular in shape and has at the lower endthereof and integral, therewith; a hook 10 spaced ,from the plateandextending upward parallelwith the `face thereof. ariectangular,relatively thin, hollow member( 11 havinga slot 12 infone-side thereofand with one end open until the two parts of the connection are joined,is soldered, cast7 or otherwise attached to astrip or plate of metalconstituting a part of the artificial denture. The parts of theconnection are attached together to be used by lSliding the hollowmember over the hook and then bending up at a right angle to the planeof the hollow memberand part lllof said hollow member, as indicated inFigures 4 and 7.

in theform of connectionshown in Figures 6 and 7 the hook and the plateform a hinge. This hook 15 instead of being an integral part of theplate is attached thereto to form a hinge. The hinge is constructed byforming at the bottomr of the plate9 an eXtension'curved to adapt `it tobeinserted in two openings 17 in the hool. The hook, therefore; swingson1 an axisv 18 made yby the narrow piece of metal between the twoopenings. The hook may be attached to or removed from the plate duetothe opening between the end of the curved extension and the part fromwhich it extends.

The construction and manner of using my device will be apparent from thedescription given and the drawings referred to. The clasp part may beproperly fitted to the tooth and the plate may then be attached theretoin the desired position. The artificial denture may be fitted to the gumand This plate may be` attached in;

the attaching member may be properly adjusted. The two parts whencompleted4 may then be joined by inserting the hook-into the hollowrectangular member and then closing the opening in the rectangularmember by `bending up the extension of one of the sides thereof asindicated.

-Having described my invention what I olaimas newanddesire to protectLetters Patent is:

v"lf An attachment for artilicialV dentures a plate atta'fchedv to meansre-A Y connected-with anatural tooth and tenda an upturned hook at oneend of said plate and axhollow member attached to a enture bodyandadapted to form a movable connection with said hook.v

An attachment for artificial dentures comprising afplate attached tomeans removably*v connected with a natural tooth and having'a hook atone end of said plate, said hoolf'spaced awayY from said plate and eX-upward parallel withthe tace of jate anda hollowY member having a`slot"ii"one sidev thereofv attached to a denture body and adaptedytoto-rma Vmovable connection with saidhook.

attachment for artificial dentures prising a plate attached toy meansref having "a hinged hook at one end oi said Vplate,saidn hookspacedfaway from said platev and- 'extending upward parallel with the'faceof'saidplate and a hollow member having a Vslot lin ione sidethereof attached touafdenture bodyl and adapted to form a connectionwith said-hinged hook.

i bIn anartiiicial dent-ure a denture body and meansto attach said bodyto a natural toth'comprising a clasp having a hinged hookattachedfthereto, whereby said hook niaymbe'" moved angularly withrespect vto the face oi; saidclasp, said' denture body Y clasphavi'ng ahinged hook attached thereto,

blyconnected with a natural tooth and said hook having the point thereofof greater diameter than the shank thereof, said point beingsubstantially rectangular andhaving the corners rounded whereby rockingmove- Vment between the clasp and the denture is formed, said denturebody having a slotted hollow member attached thereto, said hook beingadapted to form a sliding connection with said hollow member andlmeansto fasten said hook and said hollow member together.

6. A device of' the character described,

consisting of means to connect an artiiicial.

denture to a natural tooth, said means comprising a removable member onsaid tooth,

a hook attached to saidl member, said4 hook spaced away from andextending upwardV andrmeans to'fasten said-hook and said hol-V lowmember together.

7. A device of the, character described, consisting of means toconnectan artificial denture to a natural tooth, said means comprising aremovable member on said' tooth, a hinged hookV attachedvto said member,said hinged hook spaced away from and eX- tending upward from`the bottomof said member, said hinged hook having a narrow shank and enlargedhead, said head being substantially rectangular and having the cornersrounded, a slotted hollow member attached to saidartiiicial dentureadapted to receive. said hinged hook therein to forma slidable, androtatable ,connection between saiddent-ure and said tooth and means tofasten said hinged hook and said hollow member together.

8; An attachment for an artificial denture comprising a hollow slottedmember and` hingedl hook member secured to lsaid slotted member. Y

In testimony whereof I aiiix my signature.
